LT1964EDD#PBF

Introduction

The LT1964EDD#PBF is a voltage regulator designed for linear voltage regulation applications. It is a monolithic integrated circuit designed with a built-in low dropout (LDO) linear regulator. It is a fullyFeatured device built on a standard linear architecture and can offer high output accuracy and fast transient response. Its wide operating voltage and current range makes it suitable for a wide range of applications where high current accuracy and low noise is required.

Features

The LT1964EDD#PBF has a wide input voltage range of 4V to 28V, a wide output voltage range of 1.2V to 24V, and a wide operating current range of 0.2A to 5A. It has low output noise of less than 20mV at full load, which is much lower than most other linear voltage regulators in its class. It also has an internally trimmed temperature-compensated reference voltage, giving it high output accuracy of ±2%.

The device also boasts a fast transient response. With the use of innovative slew rate control technology, it can offer a fast regulation time of 1.2ms. This technology makes it ideal for applications that require fast regulation such as in data processing and telecommunications systems.

Another benefit of the device is its low dropout voltage, which is only 0.2V at full load. This feature makes it suitable for powering subsystems or providing isolation during power up and power down. It also provides a low supply current of 0.5mA at no load, making it ideal for applications with tight board space considerations.

Applications

The LT1964EDD#PBF can be used in a wide variety of linear voltage regulation applications such as microprocessors, DSPs, FPGAs and other digital and analog circuits. It can also be used in automotive, medical, industrial, networking and consumer electronics applications. It is also suitable for powering subsystems and providing isolation during power up and power down.

Working Principle

The LT1964EDD#PBF is a linear voltage regulator that operates on the standard linear voltage regulation principle. This means that it uses an input voltage, a reference voltage and an error amplifier to adjust the output voltage. When the input voltage rises above or falls below the desired output voltage, the error amplifier amplifies the difference, and the output voltage is adjusted accordingly. The output voltage is regulated by controlling the duty cycle of the output transistor.

The LT1964EDD#PBF also uses a current limit circuit which monitors the load current and prevents the regulator from exceeding its maximum set current limit. This makes it more efficient and reliable, as it prevents the device from being overloaded and helps extend its lifespan.

Conclusion

The LT1964EDD#PBF is a linear voltage regulator designed for a wide variety of applications where high accuracy and fast transient response is required. With its wide input and output voltage range, low dropout voltage, low noise and fast response time, it is an ideal choice for applications that require precision and speed. Its low supply current and its current limit circuit also make it a good choice for applications with tight board space considerations.
